Evaluation of a takeoff performance monitoring system display

A takeoff performance monitoring system (TOPMS) has been developed to provide a pilot with graphic/numeric information pertinent to his decision to continue or abort a takeoff. The TOPMS instrument display consists primarily of a runway graphic overlaid with symbolic status and advisory information including 1) current position and airspeed, 2) predicted locations for reaching decision speed V\ and rotation speed VR, 3) ground-roll limit for reaching VR, 4) predicted stop point for an aborted takeoff from current conditions, 5) engine-failure flags, and 6) an overall situation advisory flag that recommends continuation or rejection of the takeoff. In this study, over 30 experienced multiengine pilots evaluated the TOPMS display on the Langley B-737 real-time research simulator. The display was well received and judged easy to monitor and comprehend.
